I found this add-on in 2014 when Thunderbird reduced the size of the theme font. I only use it to change the size to 18.0, which makes the folder list, mail list, and headers comfortable to read on my widescreen desktop. Thanks Baris Derin. And thanks Happyone for providing a working add-on after the original stopped working yesterday. I can see my mail again!
I'm using TB 52.5.2 (32-bit) on Win 7 Pro.
